The Telex Aviation Intercom Dual Ear Micro Phone Headset is a professional-grade, noise-attenuating communication headset specifically engineered for the demanding acoustic environment of aircraft cockpits, flight decks, and ground support operations. Its primary function is to provide crystal-clear, two-way communication between crew members and air traffic control while simultaneously protecting the user's hearing from the damaging effects of sustained high ambient noise levels produced by engines, airflow, and onboard systems. The headset achieves this through a combination of circumaural (over-the-ear) ear cups equipped with dense acoustic sealing foam and advanced passive noise reduction materials that physically block a significant portion of external sound. This design is critical for reducing pilot fatigue and ensuring communication intelligibility during all phases of flight, from pre-flight checks to landing.

At the core of its performance is a high-quality, noise-canceling electret microphone. The microphone boom is fully adjustable and positioned close to the mouth, utilizing a unidirectional pickup pattern to focus on the user's voice while actively rejecting off-axis cockpit noise. This results in transmitted audio that is exceptionally clear and free from background interference, meeting stringent aviation communication standards. The dual high-fidelity dynamic speakers (receivers) deliver crisp, intelligible audio from the intercom and radio channels directly to the user's ears at safe listening levels, even amidst loud cockpit environments. The headset typically integrates a dual-volume control system, allowing independent adjustment for intercom and radio audio sources, which is a standard and essential feature for pilot workload management.

Constructed for durability and long-term comfort, the headset features a robust yet lightweight metal headband with a fully adjustable yoke system and soft, replaceable ear seals and headpad. It is designed for continuous wear during extended missions and is built to withstand the physical rigors of daily professional use. The electrical connection is made via a standard aviation-style plug, such as a dual U-174/U or a single LEMO connector, ensuring compatibility with a wide range of general aviation, commercial, and military aircraft intercom systems. By combining effective noise attenuation, superior audio clarity, and robust, comfortable construction, this Telex headset serves as a vital tool for flight safety and operational efficiency in the aviation industry.
